System of detecting and optimizing traffic control by using three-coordinate radar

Abstract

The invention discloses a system of detecting and optimizing traffic control by using a three-coordinate radar in the technical field of traffic control. The system comprises a radar detector, a signal control machine and a signal lamp. A data receiving module, a data analysis module, a dynamic allocation module and an execution control module are fixed in the signal control machine. The data receiving module is configured to receive detection data of the radar detector; the data analysis module is configured to store and analyze data of the data receiving module; the dynamic allocation moduleis configured to issue an adjustment command according to the data of the data analysis module; and the execution control module is configured to receive the adjustment command of the dynamic allocation module and act on the signal lamp. According to the invention, comprehensive data of the road are detected in real time based on a three-coordinate radar to provide the powerful data support; intervention on phase releasing of an intersection is performed in real time to avoid congestion; and the total phase cycle does not exceed a reasonable range.

Description

technical field [0001] The invention relates to the technical field of traffic control, in particular to a traffic control system utilizing three-coordinate radar detection and optimization. Background technique [0002] After decades of development, road traffic control has formed a relatively complete theoretical system in two ways: multi-period fixed-period control and induction signal control. The multi-period and fixed-period control method is to divide a day into multiple time periods based on historical traffic flow data, and each time period is equipped with different cycle lengths and green signal ratios according to the changing trend of traffic flow. Induction signal control is based on the point or interface real-time traffic data provided by the upstream detector of the intersection entrance, and determines whether the current green light release signal is extended or terminated according to the gap time between vehicles arriving at the intersection. In recent ...

AI Technical Summary

Problems solved by technology

The existing commonly used road traffic vehicle detectors are mutually restricted by the existing traffic signal control theory. The data provided by the detectors are basically point data or interface data on the road, which cannot provide strong data support for real-time traffic control. , resulting in very limited actual effect of the adaptive control method, which cannot meet the actual optimization needs
